APPARATUS FOR" MANUFACTURING PLATES, 8w.

To all whom it may concern:

Be it known that I, JEAN MARIE ANDRI J FAURE, of 21 Place du Champ deFoire, Limoges, Haute-Vienne, France,.have invented an ImprovedApparatus for Manufacturing Plates, &c., of which the following is afull, clear, and exact description.

, The invention is shown by way of example in the annexed drawingsinwhich:

Figure 1 is an elevation of the molding tool and Fig. 2 a crosssectionthereof drawn to a larger scale.

Fig. 3 is an elevation of the machine, While Fig. 4 is a side Viewcorresponding to the to the thickness which the blank is to have latterand illustrates a portion of the machine.

Fig. 5 relates to a modified construction. Fig. 6, is a correspondingdiagrammatic plan View.

Fig. 7 is a'partialside view corresponding to Fig. 6.

Fig. 8 is a vertical section of am-odified form of the machine.

Fig. 9 is a corresponding side view.

Fig. 10 is a horizontal section on the line A-A, Fig. 9. g

Figs. 11, 12 and 13 illustrate diagrammatically the working of themachine. 4

Figs. 14 and 15 illustrate in elevation and in side view the employmentof this device 011a lathe of the type usually employed for centering andpressing the layers of clay on the molds.

Figs. 16 and 17 aretwo sections on lines B-B and CC of Fig. 15.

The molding toolshown in Figs. 1 and 2 isconstituted bya sheet a of hardwood,

steel, gunmetal or other suitable hard sub stance ofa thickness, forexample, of .two to four centimeters. This sheet is cut away accordingto a profile 1, 2, 3, 1 obtained by tracing at a distance from the mold6 equal after, molding, a line parallel to the half profile of thismold. y i It is preferable to give to thit part of the tool which is infront of the periphery of the mold,fa slight progressive cut-away shapeas indicated by the dottedline. a The tool is rounded ofl' as shown inFig. 2 so that the blank orsheet of clay shall engage beneath the tooland that a downw ydi ct d p essure shall be produced 7c meshing withanother bevel Specification of Letters Patent.

causing theapplication of the blank against the mold and its adherencethereto.

The plane on which the profile 1,2, 3, 4 is drawnpasses through the axisof rotation of the mold at the time when the application takes place andthe point 1 is on this axls.

The movement of applying this tool to the blank is such that during thisapplication a the different points of the profile 1, 2, 3, 4 movenormally to the plane P (Fig. 2) in which the profile is traced.

These two conditions, however, are not absolute. Owing to the plasticityof the clay the tool may be constituted and moved in a slightlydifferent manner. It should be noted that owing to the rotary movementall points of the blank which are on the same circle are submitted tothe same operations, this permitting the conditions above set forth tobe departed from more or less according to, circumstances.

This molding tool is carried by a turrethead 0 (Fig. 3) on which is alsomounted a gage (Z. This turret head is furnished witha handle 6 and issecured on -.a spindle f adapted to rotate in bearingson a frame 9capable of sliding vertically in a stationary base 7t which carries theshaft z' supporting the mold b and a horizontal shaft 7' driven inanysuitable manner.

On the spindle f is secured a bevel wheel wheel Z mounted on a shaft m.c

This shaft m carries a pinion n engaging with a rack 0 adapted to slidein a groove pand providedwith a spring 9. A pivotally mounted stop 9serves to retain this rack in the set position. The frame 9 rests by aroller '8 on a cam 25 keyed to the shaft j.

The operationis as follows:

The operator, having placed the mold b carrying the clay blank to bemolded on the shaft 2', manipulates the handle 6 so as to bring themoldingtool a toward the mold. By rotating the spindle f the concurrentrotation of the shaft m and pinion a is brought about thus moving therack 0 in its slide and putting the spring 9 understress. The stop (1engages .behinda stop r carried by the rack when the latter reaches itsextreme position and retains it, at which time the molding tool occupiesits working position.

" name, n thestop then frees the racket As soon as the molding operationhas been completed the. frame rises slightly and the tool is removedfrom the clay Atthis moment a stop u carried, for example 'by the cam25, comes up againstanextension on the stop 9 and raises the latter. Therack is drawn back by its spring androtates the shaft m and spindle f.The turret h'ead ct revolves half'a revolution thus bringing thecalibrating tool above the blank. The rack coming up against the stop;77 occupies a definite position and the V ca'lihrating tool as'siunesits precise vifrorl'zin'gl position.

The cam t then alloiifs the frame 9 to again descend; the calibrationthen takes" madein two parts, The lower portion g is' unprinted to slideverticanya before, and the upper part 9? to rotate in the part gconcentrically with the shaft m. The portion g 'carries sp'ur gearing eengaging with a rack 0 arranged in the same manner as the rack 0 andprovided tv'ith similar locking and stopping mechanism. The operation inthis case is as follows:

Assiiining that after a molding and calihrating operation the p'ortiohghas beenrotated to freethe head of the latheand that the spindle f hasassumed theposition 1 '(Fig. 6); the operator having placl d anothermold in position draws toward him the handle 6 to bring thehead 0 abovethe mold. During this movement he brings about the partial rotation ofthe portion 9 of the frame and sets the rack o the same timehe setstherack ,0 for, inasmuch as theshaft fjcannot rotate inasmuch as theoperator holds the handle a, the shaft 7 causes the rotation of theshaft m; and pin- 161m. As will be seen, a single pull, on, handle issufficient to set both racks The molding is carried out asabovedescribed. As soon as it is finished the finger u sets free the ma; 0and agage is suhstitnte'd .for the moldingtool. When the calibration hehcompleted the frame. 'risest'o ne the tool and the stop 9 of tine-rack01 comes up against the fixed stop 10 carried the The rotatable portiong} then rotates and assiimes the position thiis freeing the upper partof the shaft 2'. During" this m ement of the portion are pinion rolls ene pinion vvhich iss'tationary and the tllii't head ftates half a fvlllilifiii,

It is to be understood that any kind of tool may be substituted for theball-shaped tool illustrated in Fig. 8.

Similarly, a gage may be substituted for this molding tool.

The new arrangement may be conveniently mounted on the frame of thelathe by hand and thus enable manual labor to be superseded bymechanical operation without interfering with existing conditions. Butit should be understood that the novel arrangement'is applicable to allkinds oflathes other than those above described.
